We kid you not: There is one in the Rituale Romanum
Blessing of cheese (or butter):
P: Our help is in the name of the Lord.
All: Who made heaven and earth.
P: The Lord be with you.
All: May He also be with you.
Let us pray.
Lord God almighty, if it please you, bless + and sanctify + this creature, cheese (or butter), which by your power has been made from the fat of animals. Grant that those of your faithful who eat it may be sated with a blessing from on high, with your grace and all good things; through Christ our Lord.
It is sprinkled with holy water.
